DOM:window
Da MDC.
Indice |
[modifica] Introduzione
Questo capitolo contiene una breve reference per tutti i metodi, proprietà, ed eventi disponibili attraverso l'oggetto window del DOM. L'oggetto window implementa l'interfaccia window, la quale eredita dall'interfaccia AbstractView.
L'oggetto window rappresenta l'intera finestra. Tipicamente window contiene l'elemento document come figlio, fornisce accesso agli oggetti window.navigator e window.screen per manipolare l'ambiente di navigazione, e prevede un numero di proprietà speciali per accedere al modello a oggetti sotto di esso.
Ogni tab che viene aperta contiene il suo personale oggetto window; ciò significa che l'oggetto window non è condiviso fra le varie tab aperte nella stessa finestra. Solo due metodi vengono condivisi dai vari oggetti window presenti in una stessa finestra, e sono i metodi window.resizeTo e window.resizeBy.
